Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Usually straight, occasionally wavy or interlocked; coarse, uneven texture with a dull luster and a naturally oily feel
Color Description
Heartwood is typically golden or medium brown, darkening with age. Sapwood is pale yellowish-white. Often shows distinct streaks of darker brown or black grains.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, fungi, and termites due to high natural oil content
Common Uses
Ship and boatbuilding (decking), exterior construction, high-end outdoor furniture, veneer, and turnery
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); extensively grown on plantations in Africa and Latin America
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot
Wood Age Estimate
Relatively fresh/processed; the light golden-brown color and visible machining dust suggest a recently planed or sanded board without significant UV patina.
Sustainability Status
Listed on the IUCN Red List as Endangered (natural forests); however, it is widely available as plantation-grown wood with FSC certification.
Workability
Generally easy to work but contains high levels of silica which rapidly dulls cutting edges. Glues can be difficult due to natural surface oils; solvent wiping is recommended before bonding.
Notable Features
Distinctive leather-like scent when freshly cut. High oil content makes it highly resistant to water and weathering.
Finish Recommendations
Teak oil or tung oil to maintain the natural look; if film finishes like lacquer or polyurethane are used, the wood must be wiped with acetone to remove surface oils first.
Identification Confidence
High; the characteristic golden-brown color, oily appearance, coarse texture, and specific grain streaks are hallmarks of Tectona grandis.
